The results are pretty interesting. I would have guessed that the CPC would be higher for .diamonds compared to a .com because a lot of people are still unaware of these new GTLDs and would hence click a .com more readily than one of these new gTLDs.
Also, cynically, I would have guessed Google would have artificially infused a bit of higher CPC on the new gTLDs considering people who own it already have sufficient money to have gone for these higher priced domain names in the first place.
